6 Storage
After the tractor has completed stage work, or for some reasons, needs to be stopped for a lone time (more than one
month), it shall be properly kept or sealed for safekeeping to prevent mechanical parts from corrosion, aging and
distortion.
To seal up the tractor for safekeeping, the first step is to clean the tractor thoroughly, adjust and tighten all connecting
pieces, then complete required technical maintenances in working hours to make the tractor in good technical state.
Important: During period of long-
term shutdown, it is more necessary to have a scientific storage and special
maintenance for the tractor. Otherwise, the technical deterioration time of tractor will be faster than working period.
6.1 The reasons of tractor damage in shutdown period
6.1.1 Corrosion and contamination:
during shutdown period, dusts and water vapor in the air diffuse into machine
by the cracks, holes, etc. to make the parts to be contaminated and corroded; the relative motion surfaces, such
as pistons, valve
s, bearings, gears, etc., will lose mobility and pressure protection from lubricant films after
they have been in a stationary state for a long time, thus to produce corrosion, rust, cementation obstruction or
stagnation, so scrapped.
6.1.2
Aging: The rubber, if bathed in sunshine, the rubber, plastic and other parts will be easy to aging,
deteriorating, become brittle so as to lose activation, or to be corroded.
6.1.3 Distortion: If pressed for a long time, the parts such as drive belt and tire might appear plastics distortion.
6.1.4 Others: The electric components are caused self-discharge.
6.2 Storage of tractor
6.2.1 Prior to storage, check the tractor carefully, and eliminate all existing failures to maintain it in good technical
conditions. Then clean up external surface of tractor.
6.2.2
Drain antifreeze and antirust liquid in the heat radiator, cylinder and water pump, and drain the lubricant from
power train and hydraulic oil from hydraulic system to let them run out until empty.
6.2.3
Remove the battery and the lubricating grease and store them in a dark and ventilated room at a temperature
higher than 10℃.
6.2.4 Drain the oil out of engine while it is hot, refill new oil, and allow small throttle running for several minutes,
so that the oil can evenly attach to the surface of all moving parts.
6.2.5 Apply the lubricating grease on all lubricating points.
6.2.6 Heat dehydration Vaseline up to 100~200℃, and apply it on the contacts, connectors of electric components
and on the surface of metal parts unpainted.
6.2.7
Loosen fan belt on the engine or remove it when necessary, and wrap it up and store it separately. Then spray
antirust agent in the pulley slot. Repair the paint where the paint has fallen off on the tractor.
6.2.8 Drain and clean the diesel tank.
6.2.9
Use protective material (such as canvas, waterproof cloth and oil paper) to seal up the pipe ends of engine,
such as inlet, outlet, to eliminate the entry of foreign substances, dusts and water.
6.2.10 Place all the control sticks in neutral position (including electric system switch) with the front wheel in right
direction and suspension rods in lower position.
6.2.11 Use wooden frame to support the tractor, in order to release the loads on the front wheel. And regularly check
the tire pressure.
